Orally disintegrating, sublingual and buccal formulations

ABSTRACT

The present invention is related to an orally disintegrating, sublingual or buccal formulation of active ingredient such as cannabidiol or tetrahydrocannabinol.

FIELD OF THE INVENTION

Provided herein is an orally disintegrating, sublingual or buccal formulation of an active ingredient such as cannabidiol or tetrahydrocannabinol.

BACKGROUND OF THE INVENTION

Active ingredients such as cannabidiol (CBD) and tetrahydrocannabinol (THC) may be helpful in providing relief for conditions including pain, decreasing opioid use, anxiety, epilepsy, glaucoma, HIV/AIDS symptoms, Irritable Bowel Syndrome, movement disorders such as Tourette Syndrome, Multiple Sclerosis, nausea and vomiting associated with chemotherapy, posttraumatic stress disorder, and sleep problems, and also have recreational uses. CBD and THC can be formulated into oral dosage forms, including chewable forms exemplified by gellans/gelatins like gummies, mints, and cookies. But ingesting the active ingredients in this form exposes them to the gastric contents and to first pass metabolism. This can result in inconsistent dosing and delayed and unpredictable onset of effects. This may be due to one or more of lipophilic interactions, dilution of the active ingredients, or degradation of the active ingredients. Accordingly, there is a need in the art for improved oral dosage formulations.

SUMMARY OF THE INVENTION

Provided herein is a dosage form, which may be oral. The dosage form may be orally disintegrating, buccal, or sublingual. The dosage form may contain (a) about 0.5 to 3% wt/wt of a sweetener; (b) about 6.5 to 20% wt/wt citric acid, oleic acid, caprylic acid, tartaric acid, or succinic acid; (c) about 6.5 to 20% wt/wt sodium bicarbonate, potassium bicarbonate, or potassium carbonate; (d) about 1 to 5% wt/wt sodium carbonate or calcium carbonate; (e) about 25 to 35% wt/wt silicon dioxide or calcium phosphate; (f) about 5 to 10% wt/wt cellulose, lecithin, corn starch, potato starch, pectin, or agar; (g) about 25 to 35% wt/wt dibasic calcium phosphate anhydrous; (h) about 0.5 to 1% wt/wt menthol extract; (i) about 2.5 to 7% wt/wt potassium hydrogen tartrate; and, (j) about 0.5 to 1.5% wt/wt active ingredient.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows the timing of the effects of an active ingredient formulated in an oral formulation described herein.

DETAILED DESCRIPTION

The inventor has discovered that the formulations described herein surprisingly provide rapid and improved uniformity of delivery of an active ingredient such as CBD and/or THC or an analog thereof. The formulation in particular provides advantages over other oral formulations such as gelatin/gellan formulations (“gummies”), mints, and cookies. Specifically, the inventors have discovered orally disintegrating, buccal, and sublingual formulations that avoid exposure of the active ingredients to the gastric contents and first pass metabolism, and the concomitant negative effects on delivery of the actives to their sites of action. Without being bound by theory, the formulations described herein provide rapid and consistent delivery of CBD and/or THC (or analogs or derivatives thereof) as compared to known oral formulations by avoiding negative impacts on peak concentrations, metabolic byproducts, and delayed onset of effects. The formulations described herein improve the amount of active ingredients absorbed and the rate of absorption. The improvements exhibited by the oral formulations may be due to their effervescent characteristics.

1. Definitions

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise.

For recitation of numeric ranges herein, each intervening number there between with the same degree of precision is explicitly contemplated. For example, for the range of 6-9, the numbers 7 and 8 are contemplated in addition to 6 and 9, and for the range 6.0-7.0, the numbers 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, and 7.0 are explicitly contemplated.

“About” as used herein may mean +/−15% of a recited value or amount. For amounts measured in % wt/wt, “about” may mean +/−10% of the percentage points recited. For example, about 5% wt/wt may mean 4.5-5.5%.

2. Oral Formulation

Provided herein is an oral formulation comprising an active ingredient, which may be one or more of CBD, THC, an analog thereof, a derivative thereof, and a combination of the foregoing. In one example, the THC comprises at least one of tetrahydrocannabinol and delta-9-tetrahydrocannabinol (delta-9-THC). In another example, the THC is delta-9-THC. In one example, the analog is cannabidiolic acid (CBDa) or tetrahydrocannabinolic acid (THCa). In another example, the analog is selected from cannabinol (CBN), cannabigerol (CBG), cannabichromene (CBC), cannabicyclol (CBL), cannabivarin (CBV), tetrahydrocannabiorcol (THCC), tetrahydrocannabivarin (THCV), tetrahydrocannabiphorol (THCP), cannabidivarin (CBDV), cannabichromevarin (CBCV), cannabigerovarin (CBGV), cannabigerol monomethyl ether (CBGM), cannabielsoin (CBE), and cannabicitran (CBT).

The formulation may be orally disintegrating, sublingual, or buccal. The formulation may also be effervescent. The formulation may be a powder or a solid. In one example, the solid formulation is a tablet. The solid tablet may comprise channels or perforations to increase surface area, which may provide more rapid absorption of the active ingredient. The optimal pH for the formulation, which may provide enhanced transport across the mucosa, may be about 4.5, 5, 5.5, 6.0, 6.5, or a range thereof. In one example, the optimal pH is about 4.5-6.5.

Without being bound by theory, surface charges of the active ingredient may limit the efficiency of transport through the mucosa. In addition, the lipophilic nature of the active product may limit its solubility in saliva, which may in turn limit absorption of the active ingredient. The formulations described herein addresses these limitations by creating a favorable micro-environment for dissolution of the active ingredient by including citric acid to create an environment favoring the dissolution of the active ingredient in an aqueous environment. The formulation may also promote transport of the active ingredient through the mucosa by creating a basic environment to support favorable transport of lipophilic cannabinoid molecules across the mucosa.

The oral formulation may provide an onset of effect for the active ingredient at about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 minutes after being ingested, or a range thereof. In one example, the onset of effect is at less than 3, 4, or 5 minutes. The effect may be one or more of increased relaxation, altered perception, increased appetite as perceived by the user (based on results of Kleinloog, Profiling the subjective effects of Δ9-tetrahydrocannabinol using visual analogue scales (2014)), or a combination thereof.

The oral formulation may also provide a peak concentration or a peak effect for the active ingredient at about 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, or 120 minutes after being ingested, or a range thereof. In one example, the peak concentration or effect may be at about 30 minutes. In comparison, oral formulations known in the art have an onset of effect at about 1-2 hours and a peak effect at 1-8 hours after ingestion. An effective amount, which may be a therapeutically effective amount, of the active ingredient may cross into the blood of a subject in less than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 13, 14, 15, 16, 17, 18, 19, or 20 minutes after ingestion of the oral formulation, or a range thereof. In one example, the effective amount crosses the mucosal membrane in less than about 3-5 minutes. The active ingredient may cross into the blood by mucosal absorption in the oral cavity, absorption through the gastrointestinal mucosa after being swallowed, or a combination thereof.

Example 2 Orally Disintegrating/Sublingual/Buccal Formulations Provide Rapid Onset of Effects

This example demonstrates that oral formulations described herein provide rapid onset and peak effects of an active ingredient. The effects of exemplary oral formulations described herein were measured against a control. Subjects were assigned to receive either an active (n=7) or placebo (n=1) formulation lacking an active ingredient. The subject characteristics are described in the table below.

TABLE 2 Active Placebo Sex, n (%) Male 4 (50.0) 1 (100.0) Female 3 (50.0) 0 (0.0)  Mean Age, years 34.67 +/− 11.4 32.0 +/− 0.0 Prior Cannabis User Yes Yes

The effects of the formulations were measured over a 120 minute period. No subject was lost to follow up or excluded from the analysis.

The results of the analysis are provided in FIG. 1, which shows the effects of the active over time. As shown in the FIGURE, A=acidic ingredient, where A is citric acid, and B=basic ingredient, where B is sodium carbonate/calcium carbonate. The Y-axis=0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 45, 60, 75, 90, 105, and 120 minutes. Subjects reported responses at these pre-defined time points. Virtual analog scales (VAS) measured levels of “effect” (a combination of increased relaxation, altered perception, increased appetite as perceived by the user). The STANDARDIZE tool in Excel was used to bring all data to baseline. The peak effect was set as 100 for all users, so that the effects became negative for the active ingredient group if the (average of the data points for each sample)>(individual data point).

The results in FIG. 1 indicate that basic (“B”) ingredients are key to improved effects. Overall, slopes demonstrate increased onset of action when using combinations of A and B. Steepest slopes are shown for 5% A/10% B, 10% A/10% B, 15% A/15% B. The slopes suggest fast onset of the effect of the active ingredient. Furthermore, 10% A/10% B had the fastest onset of peak effect at about 15-20 minutes.
